Assay Offices

By law all items sold as gold, silver, platinum or palladium in the UK must be hallmarked to confirm that they meet the legal standard of alloy proportionality for the precious metal they are being sold as. This can only be carried out by one of the four UK Assay Offices, or an Assay Office belonging to the International Convention. Here are where to find the four UK offices...
